[flang-dev] [Classic Flang] RFC: Adding release_12x branch to flang-compiler/classic-flang-llvm-project

[Michał Paszta via flang-dev]

Hi Bryan,

Thanks a lot for your efforts with creating this branch. I checked out both
your classic-flang-llvm-project/release_12x branch and the code in PR
#1010, that you mentioned. They both built fine for me with gcc-10, but I
got some errors from the tests I ran. I expect we should also see them in
CI, once the release_12x branch is pulled into the origin repo.

Classic-flang-llvm-project errors:

Failed Tests (4):
  Clang :: Driver/flang/classic-flang-must-preprocess.F
  Clang :: Driver/flang/classic-flang-must-preprocess.F95
  Clang :: Driver/flang/classic-flang.f
  Clang :: Driver/flang/classic-flang.f95

make install went fine despite the test failures.
With the new llvm-12 I ran the flang project tests and got this error:

Failed Tests (1):
  Flang :: f90_correct/lit/array_constructor_nested_implied_do.sh

This comes from a test I just added recently in PR#1004, so perhaps it just
needs a slight adjustment to the newer llvm tools. I can check this.

I am more worried about the llvm project failures. We do run clang and llvm
tests on every PR, but when pulling the branch as a whole we won't see them
until the first PR to the new branch is submitted for review (just like was
the case with release_11x).
Are you able to reproduce these failures on your side?

Best regards,
